Speed limit signs near mile marker 81. The speed limit upon entering South Carolina on I-77 is 60 mph (for some reason), and it remains that way for a surprisingly lengthy distance, until you are south of Rock Hill. (Photo taken 1/22/11).

Interstate 77 South at Exit 46: Road 20 / White Oak. Sorry about this picture, but with the sunlight being as bright as it was and the sign being greatly shaded by the trees, it's the best I could do. (Photo taken 1/22/11).

Interstate 77 South approaching its southern terminus at Interstate 26 - 1 mile. As the signs say, use I-26 West to get to Interstate 20 and use I-26 East to get to Interstate 95. (Photo taken 1/23/11).
